Canstruction is a United States 501 nonprofit organization providing canned food to local food banks in cities holding Canstruction competitions. Canstruction is an international charity competition where architects, engineers, contractors and students they mentor, compete to design and build giant structures made entirely from full cans of food. At the close of the competition all of the food is donated to local food banks where the competitions are held. Canstruction was founded in 1992 by Cheri Melillo and has since raised millions of pounds of food for food banks in participating cities across the world. With more than 170 cities and over 30,000 volunteers participating in Canstruction competitions, Canstruction has grown to become one of the largest food drives for food bank donations in the world.
Canstruction holds annual design and build competitions to construct structures made entirely out of canned food. In each city after the structures are built and the winners declared the creation goes on view to the general public as an art exhibit. At the close of the competitions all of the food used in the structure is donated to the local food banks for distribution to community emergency feeding programs.
